SNOW MELTING DEVICE, SNOW MELTING TANK, WELL, AND WELL CONSTRUCTION METHOD
To prevent particulates from depositing in a pumping and return well.SOLUTION: A pumping and return well comprises: a water permeable pipe having a plurality of holes in the side, disposed in a water-bearing layer; a tip reinforcing rod attached to the tip of the water permeable pipe; a drain pipe, one end of which is disposed in the tip reinforcing rod; and a water supply pipe located at the top of the drainage pipe. It is desirable for one end of the water supply pipe to be disposed in the tip reinforcing rod. It is also desirable that at least a part of the tip reinforcing rod be in the lower layer below the water-bearing layer. Further, it is desirable that at least the tip part of the tip reinforcing rod be conical shaped, pyramidal shaped, or shell shaped.SELECTED DRAWING: Figure 1
【課題】微粒子が揚水兼還元井に堆積するのを防ぐ。【解決手段】揚水兼還元井において、滞水層に配置された、側面に複数の孔を有する透水管と、透水管の先端に取り付けられた先端補強桝と、一端が先端補強桝内に配置された排水管と、排水管の上部に配置された給水管と、を有する。給水管の一端は先端補強桝内に配置されていることが望ましい。また、先端補強桝の少なくとも一部は滞水層下の下層にあることが望ましい。さらに、先端補強桝の少なくとも先端部は、円錐形状、角錐形状又は砲弾形状であることが望ましい。【選択図】図１
